19 Fig. 1: Puncture phase The advantages: • small deviation in the results • no changing of weights • no system friction • no erroneous oscillations • no manipulating hold-back collars • tests can be performed on materials from 80 g/m² up to heavy corrugated board without retro-fitting • ability to perform wet tests * These accessories require connecting elements and software to be specified according to the machine. Standard DIN 56142-2 Material corrugated board, cardboard Item numbers Puncture test rig 318619* Load cell Fmax 2.5 kN e.g. Type I, 318914 Test Program 374162 For specimens width 180 mm length from 180 mm To testing machines from zwicki-Line Fig. 2: Very close correlation between PET- and LPET-tests. Zwick Roell is working with technical paper institutes and well known industrial companies, on the industrial introduction and standardization of this test. For tests on tissues, a similar test method has been set up using a ball indenter. Zwick Roell is able to offer this test equipment.
